FOR TWISTERS.

srncrrroa'rron forming part of Letters Patent No. 721,8 dated March 3.1

Application filed July 26, 1902.

To all whom it may concern:

Be it known thatI, JOHN R. ONEIL, a citizen of the United States,residing at Hopedale, in the county of Worcester and State ofMassachusetts, have invented an Improvement in Thread-Guides forTwisters, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has forits object the production of a thread-guideparticularly adapted for twisters to guide the threads of a set as theypass from the spools on the creelframe to the delivery-rolls andmaintain such threads separated from each other.

It is now the usual practice to collect the several threads of a set ina guide-eye of pigtail back of the rolls, the collected threads passingtherefrom in a loose rope or mass to the rolls, and it is extremelydifficult for the attendant to readily observe whether or not all of thethreads of the set are passing to the rolls. This is not veryobjectionable when a comparatively large number of threads constitute aset; but when three or four threads are being twisted together theresultant thread is much weaker than it should be if for any length oftime less than the entire set enter into its composition.

In my present invention I have provided a novel guide which separatesfrom each other the several threads and maintains them separated betweenthe guide and the rolls, so that the attendant can see at a glancewhether or not all of the threads of the set are running properly, theguide also causing the threads to be delivered uniformly to the rolls,so that the twist is more uniform.

Figure 1 is a perspective view of a sufficient portion of'a twister tobe understood with one embodiment of my invention applied thereto, andFig. 2 is a partialplan view showing the relative position of thecombined guideand separator and the rolls.

The top and bottom delivery rolls a I), mounted in suitable bearings,the pigtail o for the thread or end 10 as it passes to the twistingdevices, the tongue d, and the wire leg (2', having a guide-eye d forthe thread, may be and are all substantially as illus- Serial No.117.082. (No model.)

trated in United States Patent No. 616,850, dated December 27, 1898, theseveral threads w 20 &c., Fig. 1, passing from the spools supported onthe usual creel-frame. (Not shown.)

For convenience I have shown the novel thread-guide as arranged tocooperate with a set of four threads, and preferably it is made of stoutwire, comprising an upright straight shank g, bent laterally at itsupper end to form a head, the head being corrugated or crimped in thedirection of its length to present a series of downturned open loops oreyes g g g 9 They are separated from each other by' the interveningoppositely-turned loops, and the end of the wire at the extremity of thehead is extended downward, as at g below the corrugations to form aspecies of guard, said guard being a continuation of the outer side ofthe last loop g. The shank g is secured in upright position in thetransverse bar B behind the rolls, it being understood that one of theguides islocated back of each top roll for the set of threads passingthereto. Usually the spools on the creel are mounted one above theother, and in order to secure the best results I mount the guide so thatthe head thereof is in a vertical plane at an acute angle to the axes ofthe rolls. (See Fig. 2.) The several threads of the set pass through theloops or eyes g 9 &c., as they lead down from the spools and are keptseparate from each other as they pass to the rolls, so that theattendant can readily see at a glance whether or not the set iscomplete, and if one of the threads breaks it will be shown instantlyand can be pieced up promptly. By means of the depending guard g a slackthread is prevented from leaving the guide should it slackensufficiently to swing down out of its proper eye. The threads aredelivered uniformly to the rolls by means of the 1. In a twister,delivery-rolls, and a wire thread-guide located behind them and having alaterally-extended, corrugated head, to thereby present a series ofdownturned open loops or bends to receive and guide the threads of a setand maintain the same separated from each other on their passage to therolls.

2. In a twister, delivery-rolls, and a combined thread guide andseparator mounted behind them and presenting a series oflaterally-separated, downturned open loops in a plane at an acute angleto the axes of the rolls, to receive and maintain separated the threadsof a set and guide the same on their passage to the rolls.

3. As a new article of manufacture, a thread guide and separator,consisting of an upright shank having at one end a laterallyextendedhead bent to present a plurality of downturned, open loops,substantially as and for the purpose specified.

4. As a new article of manufacture, a

thread guide and separator, comprising a straight wire shank bent at itsupper end to form a lateral corrugated or wave-like head presenting aplurality of downturned, open loops for the threads of a set, and adepending guard at the extremity of the head.

5. As a new article of manufacture, a thread guide and separator,comprising a supporting-shank and a lateral head integral therewithhaving a plurality of downturned thread-eyes open at their lower ends,to receive and maintain separated from each other the threads of a setas they pass through the guide.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN R. ONEIL.
